This is what I want to know also.
In the tutorial, no example using this ref/unref code.
Maybe Glade just want to play it safe?!

Subject: Glade and GLADE_HOOKUP_OBJECT

I'm in the process of moving my gui code away from glade
(when interface.c reaches 3000 lines the fun stops)
and I was wondering about GLADE_HOOKUP_OBJECT:

#define GLADE_HOOKUP_OBJECT(component,widget,name) \ 
g_object_set_data_full (G_OBJECT (component), name, \
gtk_widget_ref (widget), (GDestroyNotify) gtk_widget_unref)

which is called on most widgets that glade creates.

Is this really necessary? What is the reason for all this
ref/unref stuff, shouldn't gtk_widget_destroy be enough?
